With Ki; sodium carbonate In 4-methyl-2-pentanone | A.1.a Example A1 a) A mixture of 1,2,3,4-tetrahydro[1]benzothieno[3,2-c]pyridine HCl (1:1) (0.02 mol), 1,1-dimethylethyl (4-chlorobutyl)carbamate (0.044 mol), Na2CO3 (0.05 mol) and KI (catalytic quantity) in 4-methyl-2-pentanone (200 ml) was stirred and refluxed overnight, then cooled to room temperature and the solvent was evaporated. The residue was washed with water and extracted with CH2Cl2. The separated organic layer was dried, filtered and the solvent evaporated. The residue was purified by column chromatography over silica gel (eluent: CH2Cl2/CH3OH 90/10). The desired fractions were collected and the solvent was evaporated, yielding 1,1-dimethylethyl [4-(3,4-dihydro[1]benzothieno[3,2-c]pyridine-2(1H)-yl)butyl]carbamate (intern 1). |

In ethanol | 2 6-[(tert-butoxy)carbonyl]amino-2-ethoxycarbonyl-hexanoic acid ethyl ester EXAMPLE 2 6-[(tert-butoxy)carbonyl]amino-2-ethoxycarbonyl-hexanoic acid ethyl ester I: R1 =R2 =Et; R=--(CH2)4 --NHY; Y=Boc) Sodium metal (0.28 g, 0.012 mol) is dissolved in absolute ethyl alcohol (9 ml) under nitrogen atmosphere. The mixture is heated to 60° C. and malonic acid diethyl ester (3.8 g, 0.024 mol) is slowly dripped in. N-[(tert-butoxy)carbonyl]-4-chloro-butylamine (2.5 g, 0.012 mol) is then gradually added to the resulting mixture at room temperature. The reaction mixture is stirred at room temperature for 2 hours and at the reflux temperature for 6 hours, and then poured into ethyl acetate/water (1/1, v/v) (100 ml). The organic phase is separated, washed several times with water, and dried over MgSO4. The solvent is then evaporated off under vacuum (0.5 mBar) at 100° C. yielding a raw oily product which is purified by reverse phase HPLC using an RP-18 resin and eluding with an aqueous phase modified with CH3 CN (45% by volume). The compound of the title (1.31 g) is thus obtained as a pure product. |

With methanesulfonyl chloride; triethylamine; In DCM; | Methane sulfonyl chloride (1 eq) was added to a stirring solution of N-Boc propan-1 -ol, N-Boc butan-1-ol or N-Boc pentan-1-ol (1 eq) and EtJM (3 eq) in DCM. Upon completion the reaction was quenched with NaHCO3 solution. The DCM layer was dried over magnesium sulfate and concentrated in vacuo to produce a crude residue which was used crude or purified by flash column chromatography. |

The resulting mixture was allowed to stir at room temperature. After 30 min, the reaction mixture was partitioned with EtOAc (0.5 mL) and FLO (0.5 mL) and the phases were separated. The aqueous phase was extracted with EtOAc (1.5 mL x 3) and the combined organic layers were concentrated under reduced pressure.
